Code Graph Explorer -- Browse files, classes, functions, and their relationships in a tree view
Blast Radius -- See which files and symbols are impacted when you change code
Review Changes -- Automatically detect git changes and show their blast radius
Find Callers / Callees -- Trace all callers or callees of any function
Find Tests -- Locate tests for any symbol
Query Graph -- Run semantic queries (callers, callees, imports, inheritance, tests) with 8 patterns
Find Large Functions -- Identify functions or classes exceeding a line-count threshold
Interactive Graph -- Force-directed D3.js visualization of your code dependencies
Live Search -- Fuzzy search across your entire code graph with instant results
Compute Embeddings -- Generate vector embeddings for semantic search
Watch Mode -- Continuous graph updates as you work
Auto-Update -- Graph rebuilds in the background when you save files

Quick Start

Install Code Review Graph from the VS Code Marketplace.

The extension requires the code-review-graph Python CLI to parse your codebase.

# Recommended
uv pip install code-review-graph

# Alternatives
pipx install code-review-graph
pip install code-review-graph

Requires Python 3.10+.

Open the Command Palette (Ctrl+Shift+P) and run Code Graph: Build Graph.

The graph database is stored locally at .code-review-graph/graph.db and updates automatically on file save.
